ok so tonight i was talking to a girl i used to work with and found out we have been sleping with the same person for the past few months 
Her and myself had been keeping it quiet. He ended their relationship by text last night. Also last night he had a conversation we me about moving our relationship forward and getting more serious
.
I will not be moving our relationship forward atall. I didnt tell the other girl that I have been sleeping with him also and im not sure if i should or not as i dont want to upset her. But I would want to know.
I asked how often they had been seeing each other and she said about 3 or 4 times a week. I have a dd so only saw him once a week or once every 2 weeks. And when i did talk to him he acted liked he wanted a proper relationship with me. But he new that I didnt really want that as have alot going on.
Im not really sure what replies to expect, but just wanted to tell someone, I'm not terribly upset but as I like the other girl I do feel bad for her as she seems upset and I feel guilty that I have not told her. Should I tell her???
